Risk to persons as a result of strong magnetic fields
Risk of death as a result of permanent magnet fields
Even when the motor is switched off, the permanent magnets can put people with active
medical implants at risk if they are close to the motor.
Examples of active medical implants include: Heart pacemakers, insulin pumps.
• As the affected person, maintain a minimum distance of 500 mm from the permanent
With regard to the effect of strong magnetic fields on people, the DGUV rule 103-013
"Electromagnetic Fields" of the German Social Accident Insurance applies in Germany.
This rule specifies all the requirements that must be observed in the workplace. In other
countries, the relevant applicable national and local regulations and requirements must be
taken into account.
When dealing with magnetic fields, you must consider the requirements of DGUV rule
103-013 of the German Social Accident Insurance.
Handling secondary sections
The magnetic fields of the secondary sections are permanent. When you come into direct
bodily contact with the secondary sections, a static magnetic flux density of 2 T is not
exceeded.
• Observe DGUV rule 103-013, § 14 "Systems with high static magnetic fields".
Risk of electric shock
Voltage is induced at the power connections of the primary section each time a primary
section moves with respect to a secondary section – and vice versa. If you touch the power
connections you may suffer an electric shock.
• Do not touch the power connections.
• Connect the motor cable ports correctly, or insulate them properly.
